IMPROVEMENT IN PROCESSES OF ORNAMENTING CARD-BOARD.

Specification forming part of Letters Patent No. 190,997, dated May 22,1877; application filed April 9, 1877.

To all whom it may concern.-

Be it known that we, ALLS'ION ADAMS and ARTHUR BOTT, of the city andcounty of Albany, and State of New York have invented certain new anduseful Improvements in the Process of Producing Ornamental Gard- Boards,of which the following is a full and exact description:

The object of our invention is to produce, at a trifling cost,ornamental card-boards possessing all the beautiful effects of theembossed card-boards whose manufacture is attended with great expense.

The common and usual method of making the embossed card-board and paperis as follows: The design for the ornamentation is produced in raisedlines upon a cylinder or roller by engraving or other suitable means.The material to be embossed or ornamented is then placed upon-a platehaving a polished surface and passed beneath the cylinder, to whichsuflicieut pressure is applied to compress the texture of' the materialto such a degree that the surface upon which the raised lines of thecylinder bear will become glazed, so as to change the tint a shadedarker than that of the uncompressed portion of it.

The cost of producing these rollers is very great, rendering the cost ofthe card-boards too great for general use.

This class of ornamental card-boards is open to the further objectionthat its indented surface renders it undesirable for lithographicimpressions, for the reason that the lines are broken up by theindentations of the surface.

By our invention we succeed in producing an article having all theaesthetic qualities of the more costly embossed one at a triflingexpense, and one that is adapted to receiving lithographic impressionswithout destroying the lines thereof.

To carry our invention into effect, we print, with a lithographic orother printing press, an ornamental design, preferably one closelyresembling the embossed card-boards, upon card-board or paper having aplain-colored, tinted, or white surface. For the purpose of making thisimpression we substitute for the ink commonly used a transparentvarnish, which, when it is laid upon the surface, does not destroy thecolor of the surface, but simply deepens the tint to a sufficient degreeto clearly define the design, producing the exact effect of the embossedsurface without indenting the surface or producing any other unevennessthereon.

By using varnish instead of ink we are enabled to print the design uponcards of vari ous colors without being obliged to use difi'erent-coloredinks corresponding with the color of the surface of the card-board.

In order, when preferred, to deodorize the varnish, to prevent it fromimparting to the card-boards any disagreeable smell, we mix with it aportion of any of the essential oils, or the preparations producedtherefrom.

When we wish to produce a finer or more highly-finished article ofcard-board we provide the same with a coating of blanc fixe, Oremnitzwhite, and glue, or like substances used for enameling of card-board;thensubject it to a pressure between plates or rollers to smooth thesurface for the desired impression; and after the ornamental design,with a transparent or semi-transparent varnish, has been impressed, andto obtain the delicate velvety finish so desirable for fine printing,and before it is dry, we subject it to the action of rapidly-movingbrushes, and thereby obtain a highly-polished surface.

We are aware that paper has been printed with designs in size, gum, orother adhesive material for the purpose of being afterward flocked ordusted with metallic powder or dry colors, and such we do not claim,broadly; but

What we do claim is- V 1. The process herein described of ornamentingcard-board in imitation of the embossed card-board of commerce,consisting in printing thereon any desired design with a transparent orsemi-transparent varnish in lieu of the colors or inks usually employed,substantially as and for the purpose specified.

2. The process of producing ornamental designs on card-board, consistingin first providing the surface or surfaces with a coating composed,essentially, of blame fixe, Oremnitz white, and glue, or theirequivalents, then printing the desired design in a transparent orSemi-transparent varnish, and, finally, subof embossing, substantiallyas described and jeeitiiilg the surlfaee sobprinted to the aetion 3fshown. po is ing-brus es, sn stantially as describe 3.
